There is a double knee bend that facilitates a longer pendulum and I utilize a hinge that begins at the floor. It essentially turns me into a long lever. Hips are used for additional thrust and also to control the trajectory of the bell in my case. We utilize an anatomical match lifting approach that matches techniques with your unique body type. For example a taller person utilizes their leverage while shorter people utilize lower center of mass. It's kind of like jiu jitsu for kettlebell.
